PRL, ELISA
The DiaSource ImmunoAssays Prolactin ELISA Kit is a solid phase enzyme-linked immunosorbent assay (ELISA) based on the sandwich principle.
The microtiter wells are coated with a monoclonal [mouse] antibody directed towards a unique antigenic site on a Prolactin molecule. An aliquot of patient sample containing endogenous Prolactin is incubated in the coated well with enzyme conjugate, which is an anti- Prolactin antibody conjugated with horseradish peroxidase. After incubation the unbound conjugate is washed off.
The amount of bound peroxidase is proportional to the concentration of Prolactin in the sample. Having added the substrate solution, the intensity of colour developed is proportional to the concentration of Prolactin in the patient sample.
